基于炉渣结构的共存理论,建立了CaO—MnO—SiO2三元渣系组元作用浓度的计算模型,考察了碱度、温度对组元MnO作用浓度NMnO的影响.结果表明:模型计算值NMnO与文献实测活度值aMnO非常吻合,说明本模型能够较好地反映该渣系的结构本质;当B<2.0时,NMnO随着碱度的增加而增加;当碱度B=2.0时,NMnO达到最大值;当B>2.0时,NMnO随着碱度的增加而降低;在低碱度范围内,碱度对NMnO的影响更为明显;温度对NMnO的影响则不是很明显.
Based on the coexistence theory of slag structure, the calculation model of action concentration of CaO-MnO-SiO2 ternary slag system was established, and the influence of alkalinity and temperature on the concentration of MnO was investigated. The results show that the calculated values of NMnO and The measured activity value aMnO is very consistent, indicating that the model can better reflect the structural nature of the slag system; when B <2.0, NMnO increases with alkalinity; when the alkalinity B = 2.0, NMnO reaches When B> 2.0, NMnO decreases with the increase of alkalinity. In the low alkalinity range, the effect of alkalinity on NMnO is more obvious. The effect of temperature on NMnO is not obvious.
